Pain localized at or around the kneecap for years is most often anterior knee pain, commonly patellofemoral pain syndrome. This typically causes pain around or behind the kneecap that is worse with stairs, squatting, kneeling, running, or sitting with the knee bent for a long time. It can relate to hip or quadriceps weakness, altered kneecap tracking, tight muscles, or prior overuse. AAOS guidance describes these typical triggers.
Other possibilities depend on the exact spot:
- Patellar tendinopathy: pain precisely at the lower edge of the kneecap, especially with jumping, stairs, running, or a resisted straight-leg movement.
- Prepatellar bursitis: pain and a noticeable soft swelling directly in front of the kneecap, often from frequent kneeling.
- Patellofemoral osteoarthritis or cartilage-related change: more likely with age, stiffness, grinding, and pain with stairs or sitting. “Chondromalacia” refers to cartilage softening but is not automatically the cause of pain.
- Patellar instability/maltracking: a sense that the kneecap shifts, catches, or has dislocated.
- Less commonly: meniscal problems, inflammatory arthritis, referred pain from the hip/back, or a bone lesion.
Because it has persisted for over 10 years, arrange a non-urgent evaluation with a GP, sports-medicine clinician, physiotherapist, or orthopedist. An examination can localize the source; plain knee X-rays are often reasonable for chronic kneecap pain to check the joint space and osteoarthritis. MRI is usually reserved for concerning examination findings or symptoms that do not improve with appropriate treatment. Textbook guidance notes that patellofemoral pain is mainly a clinical diagnosis, while X-rays help assess the patellofemoral joint and arthritis. ROSEN's Emergency Medicine Concepts and Clinical Practice, lines 194-201.
Treatment often starts with a tailored physiotherapy program focused on hip abductor/gluteal and quadriceps strengthening, mobility, and gradual activity progression. That is generally more useful than simply resting for long periods. For patellar tendon pain, the exercise approach differs somewhat, often emphasizing progressive tendon loading. Avoid steroid injections into the patellar tendon because of rupture risk. Textbook of Family Medicine, lines 4257-4263.
Seek urgent assessment if you have any of these: a hot/red markedly swollen knee, fever, inability to bear weight, a new major injury, a locked knee, rapidly worsening pain, unexplained weight loss, or persistent night pain.
A few details would help narrow it: is the pain above, below, behind, or directly on the kneecap; what reliably triggers it; and is there swelling, grinding, instability, or locking?

NICE osteoarthritis topical NSAID knee oral NSAID safety recommendations
There is no safe or effective “once-a-week” pill routinely used for long-term kneecap pain. Taking an anti-inflammatory tablet weekly, such as ibuprofen, naproxen, diclofenac, or aceclofenac, is unlikely to prevent the pain reliably and can still cause stomach bleeding/ulcers, kidney injury, raised blood pressure, and cardiovascular risks.
For localized knee pain, the lowest-risk medicine to try is usually a topical NSAID gel, such as diclofenac gel, applied only to the painful area as directed on the package. It has much lower whole-body exposure than tablets, but it needs regular application, not weekly use. Current NICE guidance recommends a topical NSAID first for knee osteoarthritis and advises using medicines at the lowest effective dose for the shortest time; oral NSAIDs require assessment of gastrointestinal, kidney, liver, and cardiovascular risks. See the NICE recommendations.
Avoid oral NSAIDs without clinician or pharmacist advice if you have any of the following:
- Past stomach ulcer or gastrointestinal bleeding
- Kidney disease
- Heart disease, uncontrolled blood pressure, or prior stroke
- Blood-thinner use
- Asthma worsened by painkillers
- Pregnancy
- Regular alcohol use or liver disease
Do not use opioid painkillers for this chronic issue. Steroid injections are also not a weekly treatment and should not be used until the diagnosis is clear, especially if the pain is from the patellar tendon.
Given a 10-year history, the better plan is:
- Get an examination and likely a knee X-ray.
- Try topical diclofenac if suitable for you.
- Start targeted physiotherapy, especially hip/gluteal and quadriceps strengthening. This is usually more effective long term than ongoing medication for patellofemoral-type pain. ROSEN's Emergency Medicine Concepts and Clinical Practice, lines 199-201.
If you tell me your age, medical conditions, regular medicines, and whether the pain is below the kneecap, behind it, or directly in front, I can help you judge whether a topical gel is likely to be safe and suitable.

FDA Voltaren Arthritis Pain diclofenac sodium topical gel 1% drug facts directions knee 4 times daily warnings
For a small, localized area of knee pain, topical diclofenac gel is generally preferable to diclofenac tablets because much less enters the bloodstream.
Best form to ask for
- Diclofenac sodium 1% gel: common OTC or pharmacy form in many countries. Examples include Voltaren Arthritis Pain Gel and generics.
- Some countries have diclofenac 1.16% gel or 2.32% gel. The directions differ by product, so follow the package or pharmacist instructions rather than copying a dose across strengths.
- Diclofenac tablets, capsules, injections, or suppositories are not the low-side-effect option for a 10-year local knee complaint.
How 1% gel is typically used for a knee
For the US 1% prescription-strength product, the labeled knee dose is:
- 4 grams spread over the painful knee
- 4 times daily
- Maximum 16 g/day for one knee
That is a standard label dose, not a requirement for everyone. If pain is intermittent, use the smallest amount that helps, for the shortest period. The OTC US label advises use for up to 21 days unless a clinician tells you to continue. The official DailyMed product directions should be checked against the exact product and strength you buy.
It is not a once-weekly medicine. It works locally for hours, so it needs repeated application on painful days. A weekly application is very unlikely to help.
Correct application
- Apply to clean, dry, intact skin over the front/around the painful kneecap.
- Rub it in gently. Wash hands afterward, unless the hands are being treated.
- Do not put it on cuts, eczema, infected skin, or under a tight waterproof dressing.
- Avoid heat pads and prolonged sunlight on the treated area.
- Let it dry before covering with clothing.
- Do not take ibuprofen, naproxen, aspirin for pain, or oral diclofenac at the same time unless a clinician specifically says it is appropriate. Combining NSAIDs increases side-effect risk.
Possible side effects
Most common: local itching, redness, dryness, rash, or burning. Stop it if a significant rash, blistering, facial swelling, wheeze, or hives occur.
Although systemic absorption is much lower than with tablets, diclofenac gel is still an NSAID. Avoid it or check with a pharmacist/clinician first if you have:
- Previous stomach ulcer or gastrointestinal bleeding
- Kidney disease
- Heart disease, stroke, heart failure, or uncontrolled blood pressure
- Liver disease
- Asthma, hives, or allergy after aspirin/ibuprofen/naproxen/diclofenac
- Blood-thinner or antiplatelet treatment, such as warfarin, apixaban, rivaroxaban, clopidogrel, or regular aspirin
- Pregnancy, particularly after 20 weeks and especially in the third trimester
Topical diclofenac has lower blood levels than oral diclofenac, but it is not risk-free. Firestein & Kelley's Textbook of Rheumatology notes that topical NSAID systemic absorption is low; NSAID-class risks include gastrointestinal, renal, and cardiovascular effects. Recent evidence on formulations and safety is summarized in a 2025 meta-analysis.
Important limitation
Diclofenac can reduce pain but will not correct the likely underlying cause, such as patellofemoral pain, tendon pain, kneecap tracking, or arthritis. Because you have had focal pain for over 10 years, use the gel as a temporary aid while arranging an assessment and targeted exercises or physiotherapy. If it has not clearly helped after 2 to 3 weeks, do not just keep escalating it.
Okay what is better option that can be taken more than 1 day to avoid pain

NICE osteoarthritis corticosteroid injection short term relief 2 to 10 weeks guidance
There is no low-risk medicine that you can take once and expect reliable knee-pain prevention for several days or a week. Long-acting pain tablets are still usually taken daily and carry the same NSAID stomach, kidney, blood-pressure, and heart risks.
The only treatment that may provide relief for more than a day is an injection, but it should only be considered after a clinician confirms the cause.
If an X-ray/exam confirms knee osteoarthritis
A clinician may consider an intra-articular corticosteroid injection into the knee. It can reduce pain for roughly 2 to 10 weeks, but it is not a permanent fix and is not meant to be repeated frequently. It is mainly used when pain is limiting rehabilitation or when topical treatment is inadequate. NICE states there is no demonstrated long-term benefit beyond about 3 months and recommends it as support for exercise, not a replacement for it. See NICE injection guidance.
If this is kneecap tracking pain or patellar tendon pain
A steroid injection is usually not the better option, particularly near the patellar tendon, where steroid can weaken the tendon and increase rupture risk. The lasting treatment is a progressive strengthening program for the quadriceps and hip/gluteal muscles. Medication can make exercise tolerable but will not prevent recurrence on its own.
Practical lowest-risk approach now
- Use topical diclofenac gel only on painful days or for a short flare, according to your local product label.
- If the knee has not been assessed, arrange a clinician/physiotherapist assessment and plain X-ray, particularly given the 10-year duration.
- Avoid buying “joint injections,” oral steroids, or long-acting anti-inflammatory tablets for self-treatment.
If your pain is actually directly below the kneecap, especially when jumping, climbing stairs, or standing from a squat, tell the clinician that. It points more toward patellar tendinopathy, for which the injection approach differs and steroid should generally be avoided.
What if the menisci are near to torn like 1st degree at one knee and 3rd degree at other knee

AAOS meniscus tears MRI grade 3 conservative treatment surgery locking
On an MRI, these grades usually mean:
- Grade 1 meniscal signal: small internal degeneration/signal inside the meniscus that does not reach a joint surface. It is generally not considered a true tear.
- Grade 2 signal: more internal signal but still not reaching the surface. Usually degeneration, not a definite tear.
- Grade 3 signal: the signal reaches one of the meniscal surfaces. This is usually read as a definite meniscal tear, not just “near torn.”
So, if one knee is grade 1 and the other is grade 3, the grade 3 side deserves an orthopedic or sports-medicine review, particularly if you have:
- Pain along the inner or outer joint line rather than only at the kneecap
- Recurrent swelling
- Catching, clicking with pain, or inability to fully straighten/bend
- True locking, where the knee gets stuck
- Giving way after a twisting injury
A meniscus tear does not automatically mean surgery. If there is no true locking, major swelling, or blocked motion, many tears can be managed first with activity adjustment and supervised physiotherapy. The AAOS meniscus guidance says many tears do not require immediate surgery when symptoms are not persistent and there is no locking or swelling. A displaced tear causing a locked knee needs more urgent review.
How this affects your medication question
No medication can heal a grade 3 meniscal tear or prevent it worsening. Diclofenac gel can reduce pain temporarily, but it does not fix the tear. A steroid injection may reduce knee-joint inflammation temporarily in selected cases, but should not be used just because an MRI says “grade 3.” The clinician needs to match the MRI finding to your symptoms and examination, since meniscal changes can coexist with kneecap pain and may not be the main pain source.
Best next step
Bring the actual MRI report and images to an orthopedist. Ask:
- Is it medial or lateral meniscus?
- What is the tear pattern: horizontal, radial, flap, root, or bucket-handle?
- Is it displaced, and is there meniscal extrusion?
- Is there cartilage wear/osteoarthritis or a ligament injury?
- Is a structured physiotherapy trial appropriate before considering arthroscopy?
If you have a knee that is currently locked, cannot fully extend, becomes very swollen after twisting, or cannot bear weight, seek urgent assessment rather than treating it with pain medicines alone.

"Patellofemoral Pain Syndrome"[MeSH Terms] AND exercise
For kneecap pain that sounds like patellofemoral pain, this physiotherapist-led video is a good practical starting point. It demonstrates quadriceps and hip/glute exercises:
A more structured home exercise program from Loyola Medicine is here:
Start gently and stay in a tolerable pain range. Stop an exercise if it causes sharp pain, swelling later that day, locking, or a feeling that the knee will give way. The most supported approach is combined hip-abductor/gluteal and quadriceps strengthening. ROSEN's Emergency Medicine Concepts and Clinical Practice, p. section “Patellofemoral Pain Syndrome - Management and Disposition.”

Do not follow home exercises alone if the knee is locked, cannot fully straighten, has major repeated swelling, or gives way. Those symptoms need an orthopedic assessment first.
